to isomerize internal alkynes to terminal alkynes using the alkyne zipper reaction. In systematic chemical nomenclature, alkynes are named with the Greek

azide-alkyne cycloaddition (RuAAC) gives the 1,5-triazole. Unlike CuAAC in which only terminal alkynes reacted, in RuAAC both terminal and internal alkynes

have been developed, including cyclisation of mixtures of alkynes and alkenes as well as alkynes and nitriles. Trimerisation of acetylene to benzene is highly

up an isomerization equilibrium, but internal alkynes are thermodynamically favored over terminal alkynes. Potash amides, from the reaction of potassium

and some alkynes undergo polymerization by opening of the multiple bonds to produce polyethylene, polybutylene, and polystyrene. The alkyne acetylene

partly due to the variety of substituted alkynes that can be used in the annulation reaction. In particular, alkynes with substituents including alkyls, aryls

Schrock alkylidyne complexes degrade upon attempted metathesis of terminal alkynes. The critical step occurs after formation of the metallacycle and consists

(alkanes), or unsaturated, with double bonds (alkenes) or triple bonds (alkynes). If other elements (heteroatoms) are bound to the carbon chain, the most

diazonium salt and furtherly converted into alkyne by coupling with phenylacetylene. Various aromatic alkynes can be employed to yield desired disubstituted

W(CO)(R2C2)3. Because alkynes have two π bonds, alkynes can form stable complexes in which they bridge two metal centers. The alkyne donates a total of four
